+Information about pagination is useful when using the `get_section` Tera function for which the `paginator` is not available.

+See [pagination template documentation](@/documentation/templates/pagination.md) for more information on the `paginator` variable.

 ## Table of contents
 
 Both page and section templates have a `toc` variable that corresponds to an array of `Header`.
